The successful implementation of Alkyl Ketene Dimer (AKD) emulsion in paper mills is key to unlocking its full potential for enhancing paper quality. NINGBO INNO PHARMCHEM CO.,LTD. offers guidance on the practical application of AKD emulsion, focusing on achieving optimal sizing effects that lead to improved paper strength, water resistance, and printability.

The application of AKD emulsion typically involves careful consideration of the papermaking process stages. As an internal sizing agent, AKD is introduced to the pulp slurry, usually after refining and screening, but before it enters the headbox. Precise dosing is critical; the recommended dosage often ranges from 0.4% to 3% based on dry pulp weight, depending on the desired level of sizing. Maintaining a consistent pH, ideally between 7.0 and 8.5, is crucial for the efficient reaction of AKD with cellulose fibers. The use of metering pumps for continuous online addition ensures uniform distribution and consistent results. Thorough mixing of the AKD emulsion with the pulp slurry is essential to avoid localized concentrations and ensure homogeneous sizing throughout the paper sheet.

When used as a surface sizing agent, AKD emulsion is applied to the formed paper web, often in conjunction with other surface treatments. This application further enhances surface properties, providing an additional layer of water and ink resistance. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of emulsion stability and proper handling. The AKD emulsion should be stored correctly, and its use within the recommended shelf life is advised to maintain its efficacy. If the emulsion shows signs of delamination or thickening, it should not be used, and consultation with the supplier is recommended.

Achieving optimal sizing effects with AKD requires not only correct application but also an understanding of the entire papermaking system. Factors such as water chemistry, the type of fibers used, and the conditions in the drying section all play a role. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supporting its clients with technical expertise, ensuring that their AKD formulations and application processes are optimized for maximum performance and cost-effectiveness. The ability to buy AKD from a trusted source like NINGBO INNO PHARMCHEM CO.,LTD. guarantees access to consistent quality and application support.
